Java Developer Magazine on Ulitzer In the latest release of JDeveloper, specifically 11.1.1.2.0 also known as 11g Release 1 also known as Patch Set 1 also known as 11g build 5536 also known as the Shepherd build (cough cough Oracle), Oracle has included a new built in page templ... (more)

I'm happy to say that the ADF Enterprise Methodology Group is running its first UKOUG presentation this year at their annual technology conference in Birmingham November 30th-December 2nd. This is a pretty exciting development for us, as this will be the first ADF EMG session run... (more)

A common requirement in databound applications is to allow the user to view changes before they commit them to the database, showing the user both the original-old value along with the new. This gives users a chance to review their changes visually by comparing the old and new. F... (more)

Between OOW and the AUSOUG conferences it's a bit of a slow blogging time for me, while presentation preparation takes priority. With a little spare time I thought I'd share this photo of some recent booty (and before you get all excited, that's arrrrgh "Pirate" booty, not the ot... (more)

Oracle Journal on Ulitzer Regular readers already know that ODTUG in conjunction with Oracle Technology Network has invited a number of Oracle ACEs and ACE Directors to present down under. ODTUG has teamed with AUSOUG to give these world recognized presenters (in fact in all cas... (more)

Java Developer Magazine on Ulitzer In the previous post we looked at how to configure the SQLAuthenticator password encryption options. Among other encryption algorithms we discovered that on creating a user from the WLS console, WLS would create the associated user in a databas... (more)

My 2 presentations for OOW are now available for download from the SAGE Computing Services website here: SOA Lite: A taste of SOA with a smidgen of Web Services Oracle JDeveloper 11g JAX-WS Web Services: As easy as 1-2-3: XSD, WSDL, Generate! ... (more)

Oracle on Ulitzer WebLogic Server 10.3.1 supports loading user credentials and roles from a number of different sources, such as LDAP or a database, through the concept of "Security Providers". In order to work with a database table structure a "SQL Authenticator" provider is re... (more)

Once again the ADF Enterprise Methodology Group is meeting at Oracle Open World to discuss JDeveloper and ADF, and we invite you to join us. This year Simon Haslam has taken the reins and delivered not 1 but 3 sessions at OOW which is an impressive effort. Of particular interest ... (more)

Blatant plug for SAGE Computing Services. Avert your eyes now if you're not interested in the advert. I was again asked today by a fellow Oracle professional, as we at SAGE present and blog on the latest JDeveloper and APEX technologies among others, does that mean we've dropped ... (more)

Did I already post/tweet/email about Scott and his blog somewhere? I forgot. In the rush up to Oracle Open World, and moving house, I'm losing track big time of what I've done and haven't done. If I turn up to OOW without any pants you'll know why. Anyhow, Scott Wesley, a fellow ... (more)

Recently we upgraded our Oracle WebLogic Servers from 10.3 to 10.3.1, and coincidentally migrated a JDeveloper ADF application 11g to 11gR1. ADF applications require a set of libraries that must be deployed to WLS before the ADF application can run, of which we completed successf... (more)

In computing most technologies have lots of terms and acronyms to learn, it's par for the course, you get used to it. However in computer security the frustration is multiplied as there are often many different terms that mean the same thing. It makes implementing security hard, ... (more)

A while back Gerard Davison blogged some simple examples of using WS-Security Policies. Gerard's specific example dealt with the WLS policy Wssp1.2-2007-Wss1.1-UsernameToken-Plain-X509-Basic256.xml. As Gerard notes the said policy (further documented in the WLS 10.3.1 doco here) ... (more)

This blog post demonstrates creating an ADF Faces RC af:tree component that sources its data from a hierarchical database table, and supports drag n drop of the nodes. Both these topics have been discussed and demonstrated by other excellent bloggers, the core of this post is to ... (more)

This is a revisit post about two important database objects for ADF, the database objects PS_TXN and PS_TXN_SEQ. The table and sequence are used by ADF to serialize user session state to the database. An old Oracle OTN whitepaper gives the low-down on these 2 objects. Without the... (more)

A popular tool for web service testing is SoapUI. The following blog post describes how to use it for testing a simple web service, as well as setting up a series of tests and even load/stress testing. Without a doubt similar documentation is available on the SoapUI website; my p... (more)

Mostly a post to document something I keep on forgetting, hopefully useful to someone else. Under WebLogic Server 10.3.1 (and maybe present in earlier versions of WLS?), on testing a deployed web service I occasionally get this HTTP response from WLS: Error 500--Internal Server E... (more)

Each new release of JDeveloper brings an explosion of blog posts from the excited JDeveloper advocates and Oracle staff. Within a week or so all the major new features are identified and explained, leaving slow typers like me wondering what to cover to get readers excited. So for... (more)

A feature seen on some web sites is buttons to increase and decrease the text font size. While most browsers supply this functionality by default (eg. In Firefox you can press Ctrl plus or minus), giving web page buttons to do this can assist less computer literate users who may ... (more)
